On January 29, 2023 at 22:05 UTC, a magnitude 4.1 shallow crustal earthquake struck 231 km WNW of Palana, Russia, at a depth of 10.0 km and coordinates 60.0891°, 156.3740°.
Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
